Create a list of at least five expenses you would have to pay if you were going to raise a sheep for one year. You can assume that the land and the barn are available and focus just on the cost of raising a sheep. You do not need a dollar amount for the expenses; just identify what items should be included in the budget.
Answer:
Food, medication, rent of the land, doctor fee and cleaning.
Explanation:
The food, medication, rent of the land, doctor fee and cleaning are the expenses that I have to pay if I was going to raise a sheep for one year. Good feed is very important for raising an animal in order to get good products from that animal. Medication safes the animal from infection and other diseases that lowers the quality of that animal. I have to pay the rent of the land on which I raise that sheep and also pay doctor fee for their checkup.

why does flowing water deposit the largest particles first
Answer:
Deposition by Water
Flowing water slows down when it reaches flatter land. ... The water starts dropping the particles it was carrying. As the water slows, it drops the largest particles first. The smallest particles settle last.

B
Answer:
B
Explanation:
Blood type is shown in the picture is B positive.
What do you mean by blood type?
"A blood type is a classification of blood, based on the presence and absence of antibodies and inherited antigenic substances on the surface of red blood cells."
What are the main blood types?
There are 4 main blood types or groups defined by the ABO system:
blood group A – has A antigens on the red blood cells with anti-B antibodies in the plasma.blood group B – has B antigens with anti-A antibodies in the plasma.blood group O – has no antigens, but both anti-A and anti-B antibodies in the plasma.blood group AB – has both A and B antigens, but no antibodies.

Explanation:
Suppose you are given an unknown solution and you need to test its pH. The pH meter is broken, and all you have is the indicator bromothymol blue to use. You add two drops of bromothymol blue to 10 mL of your unknown, and the solution turns a bright yellow. Which of the following is the best estimate of the pH of the unknown solution?
a. 8.5
b. 11.5
c. 1.5
d. 7.0
Answer: The best estimate of the pH of the unknown solution is 1.5. Option C.
Explanation:
A substance which shows different colours in acidic and basic media is called an indicator. Typical examples of common indicators includes:
--> Litmus: colour in acid ( red), colour in base (blue) and colour in neutral (purple).
--> Methyl orange: Colour in acid (red), colour in base (yellow) and colour in neutral (Orange).
--> Phenolphthalein: Colour in acid (colourless), colour in base (pink) and colour in neutral (colourless).
--> BROMOTHYMOL BLUE: Colour in acid ( yellow), colour in base (blue) and colour in neutral (green).
The indicators are themselves weak organic acids or bases and hence slightly dissociated in solution. The colour of the indicator at any given point depends on the relative proportion of the dissociated ions to the undissociated molecules since they have different colours.
From the question, since the pH meter is broken, and the pH of the unknown solution is to be determined,using an indicator instead. The best estimate of the pH of the unknown solution is 1.5. This is so because BROMOTHYMOL BLUE is blue when the pH is greater than 7.6, green when the pH is between 6-7.6, and yellow when the pH is less than 6. And pH value of 1.5 is less than 6, indicating the solution is very acidic.
At the end of a sunny day, Cindy turns on an electric fan to cool off her room. When she turns off the fan a little later, she notices that the area around the motor is warmer than it was when she turned on the fan. What is the most likely explanation for this?
1.Electrical energy was transformed into heat and energy of motion.
2.Solar energy was transformed into heat and energy of motion.
3.Solar energy was transformed into electrical energy and heat.
4.Electrical energy was transformed into sound and light.
Answer:
One
Explanation:
Because it never says that the fan used solar energy and 4 wouldn't make it heat up.

Punnett squares provide an easy way to predict the possible genotypes for an offspring, but it is not practical to perform a Punnett square analysis on all possible combinations of all members of a population to predict what the population might look like in the future.
a. True
b. False
Answer:
True
Explanation:
There are certain limitations associated with the Punnett Squares. They are not useful in case of complex genetic inheritance such as linkage between two genes. In case of linkages it becomes difficult to estimate the distribution of genotypes and phenotypes. For example in case of Nail-patella Syndrome and gene associated with blood group two genes lie on the same chromosome in close vicinity and hence there are high chances of inheritance of these traits in the offspring from the parent thereby causing random distribution of the two traits. This random distribution cannot be captured through punnet square.
The same problem is associated in case where a single gene is determined by multiple genes with graded effects of each gene.
